Hey guys, I have been putting together a build for my dad and I wanted to go with the AMD Fusion chips since he doesn't require a separate GPU, but still needed a decent graphics capability for editing videos and such. Anyways, I went with the Foxconn A75A motherboard originally. The build did not boot when all the components were in, and the PSU tested fine. We RMAed the board and got the GIGABYTE GA-A75-UD4H FM1 AMD A75 motherboard instead. When outside the chassis, the motherboard boots up with all the components connected. When I screw the motherboard onto the standoffs, it no longer boots. At first I figured it was a problem with the screws not having plastic washers between them and the holes to the standoffs, but even after putting a plastic washer on each of the holes, it still won't boot up. I short the two two prongs to do a Clear CMOS and when I press the power button, everything lights up for about 1/10 second, and immediately turns back off. All the standoffs are used, and I can't see any metal touching the motherboard. I'm at a complete loss. It is my dad's work computer, so I've been a bit rushed to get it together so he is able to continue working, but I've been troubleshooting for nearly a week now. Any ideas?
Here's the build:
